A kindred can be either omnilateral, including all of one's relatives, or restricted, which excludes some relatives by one or more criteria. Any person's omnilateral kindred includes his parents, both sets of grandparents, and so on bilaterally back through the generations. It also includes his children, his grandchildren, and so on. In addition, it includes his parents' siblings, his cousins, and their children.
